a
The wet bulb temperature condition is not required when testing units which do not evaporate condensate.
b
When using the calorimeter room method, pressure equilibrium between indoor and outdoor compartments shall be
obtained by introducing into indoor compartment, air at the same rating temperature conditions.
c
The pressure difference between the two compartments of the calorimeter room shall not be greater than 1,25 Pa.
This pressure equilibrium can be achieved by using an equalising device or by creating an open space area in the
separation partition wall, which dimensions shall be calculated for the maximum airflow of the unit to be tested. If an
open space is created in the partition wall, an air sampling device or several temperature sensors shall be used to
measure the temperature of the air from the outdoor compartment to the indoor compartment
